Description

Technical Field

[0001] This utility model relates to the field of new energy storage technology, and more specifically, to a liquid-cooled pipeline flow uniform heat dissipation device based on an energy storage system. Background Technology

[0002] Currently, centralized energy storage systems mainly use air cooling and liquid cooling to regulate the temperature of modules, keeping them at their optimal operating temperature as much as possible.

[0003] The liquid-cooled energy storage system mainly uses liquid-cooled units as the cold source, water-glycol coolant as the refrigerant medium, liquid-cooled pipes as the fluid carrier, and battery modules as the heat source. The modules are equipped with liquid-cooled plates, and the plates contain liquid-cooled pipes.

[0004] Currently, most liquid cooling pipelines on the market distribute flow by using equal-diameter primary pipes, equal-diameter secondary pipes, and equal-diameter tertiary pipes. This design does not show uniformity differences when the flow path is short, but in the long flow path of a centralized energy storage system, it will cause the modules near the liquid cooling unit to be colder and the modules at the farthest end to be hotter. This will cause the temperature uniformity of the modules to exceed the allowable range, which will cause uneven charging and discharging efficiency of the battery cells. Moreover, they are often made of thermo-fusion integral molding or stainless steel pipe connection, which is troublesome to install and maintain and can no longer meet people's usage needs.
